Hi HiveMind
I am redoing all my doors much like the Bunnings video https://www.youtube.com/watch?v=y8HsanUm9qA and as part of that process remove the door knobs and hinges (to be replaced with fancy brassy ones). All going well until I got to the second door!
The screws were in SO tight that I stripped the screw heads (which were partially damaged already). I've tried some manual methods such as prying them out (knowing I could fix any damage to the door itself - only slight movement), hammering the actual hinge out (with the hope the screws would come with it - nope. But the hinge did come off so I have more screw length to play with), WD40 and a pair of pliers - nope, trying a rubber band and a screw driver, trying a standard screw driver in the hole - all no luck. I bought a screw removal kit (you can see in the pic with a removed screw which is the same as the stuck ones). I didn't have the screw with me and feel like the removal kit may be too gig for the screw? I tried drilling with the supplied drill bit into the screw but the bit won't turn. I could be compounding the error with incorrect settings on my drill but did a test drill on a bit of wood and seemed okay. Help! Signed 'Frustrated but Not Beaten.'
